Análisis de las presiones ejercidas dentro del socket durante el ciclo de la marcha en pacientes con amputación transfemoral

Abstract

The project relies on an algorithm that combine two technologies, one involved Tekscan pressure sensors, and the other Biometrics electrogoniometers. Eight male transfemoral amputees subjects were assessed on the treadmill during five minutes in three series in their own comfortable walking speed. The pressure was measured dividing the stump in four areas two anterior, and two posterior. The two anterior areas were identified as the peak pressure, however depending on the gait cycle the pressure distribution changes at several sites at the stump-socket interface. The pressure-goniometry system algorithm could improve the dynamic stump pressures within the socket evaluation and become useful for dynamic transfemoral prosthesis assessment. © Springer-Verlag Berlin Heidelberg 2007.
